The Armstrong 1/2" drive sockets are manufactured to industrial specifications assuring a thin wall design with precise nut end dimensions. The Armstrong 1/2" drive sockets encorparates a radius corner design that engages the flats of the fastener, not the corners, providing 15 percent - 20 percent more torque.
Features:
- Radius corner design engages the flats of the fastener, not the corners, providing up to 15 percent -20 percent more torque while reducing fastener rounding, enhancing the turning of worn fasteners
- EYE-D markings optimize size visibility, also providing SAE / Metric differentiation
- Unique socket retention method, cold form ball recess, provides consistent secure retention of the socket to the drive tool eliminating the possibility of either a loose fit or tight fit
- Socket wall dimensions are optimized to provide strength while retaining access to restricted fasteners
- Manufactured from high alloy steel using the most Up-To-Date manufacturing process and heat treat for greater strength and durability
- Specifically heat treated for the correct balance of strength and durability
- Laser etched markings optimize the size identification
- 12 point Drive type
